Characteristics of truncated channelized NRD-guide

The truncated channelized NRD-guide is proposed in this paper and the corresponding characteristics are evaluated. General purpose characteristic equations are derived which actually include special cases of conventional NRD-guide, channelized NRD-guide as its simpler applications. The crosstalk can be reduced to some extent and the bandwidth is wider. The choice of different dielectric materials can optimize the required performance. Some numerical examples are given.
